  r326985 | rmudgett | 2011-07-07 20:08:05 -0500 (Thu, 07 Jul 2011) | 12 lines
  
  Some code cleanup in pbx.c
  
  * Mostly comment and format changes.
  
  * ast_context_remove_extension_callerid() and ast_add_extension_nolock()
  will write lock the found specific context.
  
  * ast_context_find() will now tolerate a NULL name.
  
  * Eliminated some inlined versions of find_context() and
  find_context_locked().
